[M4IF Technotes] How is FGS used?

[Roland Bengtsson]

I wonder how the FGS profile is used? I have read about the profile and how 
the enhancement layer is divided in several bitplanes so the client can 
choose how much it will use depending on available resources. But what is 
included in these resources?
CPU-power? Yes this seems to logical if the client don't have the power to 
show all the bitplanes it can show only some basic video stream.
Bandwidth on network? I don't see how FGS can be used here because if the 
server send all the bitplanes to the server it may already use too much of 
the bandwidth... The videostream must be cut on the server to minimize the 
use of the network.
Or have I missed something important here?
